02:51 Let’s practice how to pronounce the letter ث {tẖāʾ}.

The Arabic letter ث (tẖāʾ, also commonly transliterated as thāʾ) is the 4th letter of the Arabic alphabet. It represents the voiceless “th” sound found in the English word think. Unlike the letter ت (tāʾ), which produces a hard t sound, ث is pronounced by placing the tip of the tongue lightly between the upper and lower front teeth while allowing air to pass through. This sound can be challenging for beginners because it does not exist in many languages, but with regular practice it becomes much easier.

Basic Information

• Arabic Letter: ث
• Name: ثاء (tẖāʾ or thāʾ)
• Alphabet Position: 4th letter
• IPA Pronunciation: /θ/
• English Approximation: th in think, three, thank
• Connects to Other Letters: Yes
• Number of Dots: Three dots above

How to Pronounce the Letter ث

The letter ث is pronounced exactly like the th sound in the following English words:

• think
• thank
• three
• thumb
• theater

It is not pronounced like:

• t in top
• s in sun
• th in this (that sound is represented by ذ in Arabic)

Step-by-Step Pronunciation

1. Place the tip of your tongue gently between your upper and lower front teeth.
2. Leave only a small portion of the tongue visible.
3. Push air gently between your tongue and teeth.
4. Do not vibrate your vocal cords.

The sound should be a soft:

thhhhh

rather than:

t or s.

Is ث a Voiced or Voiceless Sound?

The letter ث is a voiceless dental fricative.

Although this term sounds technical, it simply means:

• The tongue lightly touches the teeth.
• Air flows continuously through the small opening.
• The vocal cords do not vibrate.

Compare these English examples:

The only difference is that ذ uses your voice, while ث does not.

How to Write the Letter ث

Learning to write the Arabic letter ث is straightforward. The letter ث has the same basic shape as ب and ت, but it is distinguished by three dots placed above the letter.

Writing Steps

1. Draw the curved body of the letter.
2. Finish the horizontal stroke smoothly.
3. Add three evenly spaced dots above the letter.

Remember this simple comparison:

The body of all three letters is identical. Only the number and position of the dots change.

Letter Forms

Like most Arabic letters, ث changes its shape depending on where it appears in a word.

Since ث connects to both the preceding and following letters, its appearance changes accordingly.

Examples:

• ثَمَر (tẖamar) — fruit
• مَثَل (maṯal) — example
• بَحْث (baḥth) — research

Common Words with ث

Practice reading these common Modern Standard Arabic words:

Read each word slowly, paying attention to the soft th sound at the beginning.

Similar Arabic Letters

Many beginners confuse ث with other letters because they have similar shapes or similar sounds.

Keep these differences in mind:

• ت is a hard t sound.
• ث is the soft th in think.
• ذ is the voiced th in this.
• س is a regular s sound.

Common Pronunciation Mistakes

Because the /θ/ sound is absent from many languages, learners often replace ث with another sound.

Mistake 1: Replacing ث with ت

❌ تلاتة

✅ ثَلَاثَة

Mistake 2: Replacing ث with س

❌ سَلْج

✅ ثَلْج

Mistake 3: Replacing ث with ذ

❌ ذَلَاثَة

✅ ثَلَاثَة

Whenever you pronounce ث, remember to keep the tongue gently between the teeth and let the air flow naturally.
